The NFS50 series can regulate on the auxiliary outputs down to no load making it suitable for applications that require a heavy logic load on the main 5V output and low nominal loads with high peak capability for drives, relays or switches on the auxiliary outputs. The NFS50 provides 50W of output power with free air convection cooling which can be boosted to 60W with 20CFM of air. Standard features include overvoltage and short circuit protection. The series, with full international safety approval and the CE mark, meets conducted emissions EN55022 level A. The NFS50 series is designed for use in low power data networking, computer, telecom and industrial applications such as POS terminals, servers, PABX's, industrial PC's and process automation.

During peak loading output may go outside total regulation limits. Maximum output during peak loading is 60 Watts. - 3 Forced air, 20 CFM at 1 atmosphere. - 4 Figure is peak-to-peak. Output noise measurements are across a 50MHz bandwidth made using a 12” twisted pair, terminated with a 47μF capacitor. - 5 Total regulation is defined as the static output regulation at 25°C, including initial tolerance, line voltage within stated limits and output voltages adjusted to their factory settings. Also, for stated I(2) regulation: I(1)/I(2)≤5. - 6 A minimum load of 0.5 Amps is required on the +5.1V output to obtain full current from the -12V output. - 7 Derating curve is application specific for ambient temperatures > 50°C, for optimum reliability no part of the heatsink should exceed 110[o] C and no semiconductor case temperature should exceed 115[o] C. |PIN CONNECTIONS|PIN CONNECTIONS| |---|---| |J1|NFS50-7608J| |Pin 1|AC Line| |Pin 2|AC Neutral| |J2,J3,J4|| |Pin 1|-12V| |Pin 2|+12V| |Pin 3|Return| |Pin 4|+5.1V| |E1|| |Pin 1|Ground| - 8 Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements. - 9 Three orthogonal axes, random vibration, ten minute test for each axis. 10 A 5 Watt minimum load is recommended to achieve design MTBF. - 11 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. - 12 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. ## AC mating connector Molex 09-50-3031 or equivalent with Molex 08-50-0105 or equivalent crimp terminal. ## DC mating connector Molex 22-01-1043 or equivalent with Molex 08-50-0031 or equivalent crimp terminal. **==> picture [178 x 139] intentionally omitted <==** **----- Start of picture text -----**
